There are many lewis structures you could draw for sulfuric acid, h2so4 (each h is bonded to an o). part a what lewis structure(s) would you draw to satisfy the octet rule? draw the molecule(s) by placing atoms on the grid and connecting them with bonds. include all lone pairs of electrons.

Structure 1 is satisfying octet rule because each atom surrounded by 8 electrons:
The valance electron for oxygen is 6, for sulfur is 6, but for hydrogen is 1. Therefore, the molecule has valance electrons. Sulfur is bonded with 4 oxygen atoms,  4 single bonds, whereas 2 hydrogen atoms are bonded with 2 oxygen atoms. 

But the actual structure is 2 but it violates octet rule since S is surrounded in this case with 12 electrons

The formula is (nh4)2co3
